CWE-119Published: November 18, 2005· Updated: Jun 16, 2026
4.6
CVSS v3.1
Official Description
Off-by-one buffer overflow in pnmtopng before 2.39, when using the -alpha command line option (Alphas_Of_Color), allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted PNM file with exactly 256 colors.
Technical Analysis
CVE-2005-3662 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
